Resumen

The hybrid orbit propagation methodology is used to model the error of any type of orbitpropagator with the aim of improving its perturbation model or integration technique andhence enhancing its accuracy. In this work, we present an application of the hybrid meth-odology, in which the time-series forecasting process is performed using deep learningmethod to SGP4. We have adjusted the resulting Hybrid SGP4 propagator, HSGP4, to thecase of Galileo-type orbits. We will describe the hyper-parameter selection, which is animportant part of the development of HSGP4, and show how HSGP4 can improve theaccuracy of SGP4.
